For toning your thighs, my aunt showed me something from back in her cheerleading days. Sit on the ground with your legs in a V, as if you were about to do toe-touches. Lift your legs of the ground, staying straight, without supporting yourself with you hands. Keep your back straight, too. You'll probably only be able to lift them a few inches. Lift for two counts, hold for five, and lower for two. Remember that control when you lower them is key as well- that builds a lot of muscle.
